Not a happy dyno...my M3 put down around 278 RWHP stock and my 335 did 281 RWHP stock. Obviously the 335 has a huge torque advantage and my M3 has pretty much everything short of cams and traps around 111-112mph. My 335 put down almost 345 RWHP and is over 400 lb/ft and it still pulls my M3 from a roll especially under 80mph or so. The M3 still pulls up higher especially in the triple digits but it's also about 300 lbs. lighter than my 335. The hole shot is all about the driver but my M3 is easier to launch but it has bigger stickier rubber on it too.

111-112 traps are very impressive for an NA M3, what ET did you hit, any time slips?

I think your weight reduction did alot for you. Lee Mathews trapped 112 with a completely stock exhaust, bolt on's and drag skinnies with alot of weight reduction, no way he was making 320WHP, that guy def had driving skills though.
